CABLE-TRACK SUPPORT.

' Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed February 23, 1910. Serial No. 545,399.

To all whom it may concern:

Be it known that I, WILLIAM T. BUCK, a citizen of the United States,residin at Vliets, in the county of Marshall and S tate of Kansas, haveinvented a new and useful Improvement in Cable-Track Supports, of whichthe following is a specification.

This invention relates to certain new and useful improvements in cabletrack sup ports, especially adapted to be used in connection with mymail carrier, the object being to provide means for supporting the cabletrack in such a manner that the supporting wheels of the carrier and theretaining wheels can readily pass over the same.

Another object of my invention is to provide a cable support which is soconstructed that the cable will be securely fastened thereto, so as toprevent the same from becoming detached, and at the same time a supportis formed in which the cable is so mounted that the carrier can passover the same smoothly.

A still further object of my invention is to provide a cable supportwhich is carried by a cross arm supported by braces in such a mannerthat the cable support would be held firmly in position thereon, invertical alinement with the operating cable.

Another object of my invention is to provide a cable support which isexceedingly simple and cheap in construction and one in which the cableis held in the cable receiving groove by the tension of the samein sucha manner that after the cable has been sprung into position all dangerof the same jumping out is prevented.

With these objects in view the invention consists of the novel featuresof construction combination and arrangements of parts hereinafter fullydescribed and pointed out in the claims.

In the drawing forming part of this speci- 1 fication: Figure 1 is anend elevation of an intermediate post showing my improved cable tracksupport arranged in position thereon. Fig. 2 is a side elevation of myimproved support showing cable secured in position. Fig. 3 is a top planview of the cable support the cable being removed. Fig. I is a verticalsection through the same and Fig. 5 is a vertical section taken on line44 of Fig. 2.

In carrying out my improved invention I employ a cross bar A, having acentral opening through which a bolt is adapted to pass,

for securing the same in position on one of the intermediate posts andsaid cross bar A is providedwith outwardly extending bolt portions, B onthe end of which is mounted my improved cable support C which is lockedthereon by riveting the end of the bolt. The cross bar A is supported bybraces A, the free ends of which are overlapped and apertured, throughwhich a screw or bolt is adapted to pass for securing the same to thepost above or below the cross bar and in Fig. 1 I have shown the bracessecured above the cross bar but it is of course understood that they canbe secured in any position desired.

The support O comprises a block having a straight edge C and a curvededge C one face of the block being cut away or reduced in thickness toform a central enlargement G which is undercut at C in which is adaptedto fit a cable D for holding the same in position on the support. Thecut away portion of the block forms a groove which extends upwardly andcommunicates with grooves E formed in the straight edge of the block inwhich the cable is seated as clearly shown and these grooves are of sucha depth that the cable can be supported in such a manner that a smoothtrackway will be formed for the supporting wheel of the carrier in orderto allow the wheels to ride over the same smoothly as it was seen thatwhen the wheels leave the cable they will ride on the straight'edge ofthe block until brought into engagement with the cable again. The curvededge of the block forms two inclined trackways for the retaining wheelsof the carrier so that the wheels will be led back on to the cable trackafter passing over one of the supports.

The bolt portions 13 of the cross bar A are cut away to conform to theunder-cut portion of the central enlargement of the support in order toreceive the cable track and it will be seen that after the track hasbeen sprung in position in the grooves of the support it will be heldtherein without any danger of the same jumping out.

In the drawing I have shown the supports C arranged with their straightedges on top but it is of course understood that the supports could bereversed so as to bring the curved edges on top whereby the sup portingwheels will ride up the incline track ways in such a manner that theywill pass over the same without any danger of the carriers becomingcaught by the supports or the carr1ers ump1ng the track. I have alsoshown the supports C arranged on the cross arm with their grooved faceson the inside but it is of course understood that the blocks can beturned so as to throw the grooved faces on the outside and the supportsused in the same manner. 7

lVhile I have shown and described certain details of construction ofsupporting arm it is of course understood that various changes can bemade without departing from the spirit of my invention.

What I claim isf 1. A cable support comprising a block having a curvedgroove formed onits face, and provided with a groove in its upper edgecommunicating with the groove in its face.

2. A cable support comprising a block having a straight edge and arounded edge, said block being cut away to form a central enlargement,having an undercut edge, said cutaway portion communicating with groovesformed in one edge of said block.

3. The combination with a cross bar having rounded ends, of a blockhaving a central opening to receive the rounded end of said cross bar,said block being provided with a straight edge and a curved edge, theface of said block being cut away to form a central curved enlargementhaving an under cut edge said cutaway portion communicating with groovesformed in the edge of said block, the under edge of said rounded portionof said cross bar being cut away to receive a cable when sprung into thegrooves of said block.

4:. In a cable track support, the combination with a post carrying across bar having rounded outer ends, braces connecting said cross bar tosaid post, of blocks mounted on the ends of said cross bar and securedthereon by riveting the ends of said cross bar, said blocks being cutaway to form a cable receiving groove in one face communicating withcable receiving grooves formed in the edge of said block.

5. The combination with a cross bar adapted to be secured to a post, ofcable supports mounted on the ends of said cross bar, said cablesupports comprising blocks having curved and straight edges said blocksbeing provided with grooved faces communicating with grooves formed inthe straight edges of said block into which the cables to be supportedare adapted to be sprung.
